(1) The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not ensured.
(2) Typical values represent most likely parametric norms for V_CC = +3.3V and T_A = +25°C, and at the Recommended Operation Conditions
at the time of product characterization and are not ensured.
(3) Specification is ensured by characterization and is not tested in production.
(4) t_SKD1, |t_PLHD − t_PHLD|, Pulse Skew, is the magnitude difference in differential propagation delay time between the positive going edge and
the negative going edge of the same channel.
(5) t_SKD2, Channel to Channel Skew, is the difference in propagation delay (t_PLHD or t_PHLD) among all output channels in Broadcast mode
(any one input to all outputs).
(6) t_SKD3, Part to Part Skew, is defined as the difference between the minimum and maximum differential propagation delays. This
specification applies to devices at the same V_CC and within 5°C of each other within the operating temperature range.
